However, disassembling such multilayered systems without damaging the constituent materials remains a challenge, particularly for recycling or repair purposes. Magnetic pulse technology offers a promising solution by generating transient mechanical loads through Lorentz forces induced in conductive layers. This paper aims to define the operating conditions of a high-power pulsed (HPP) generator capable of inducing controlled delamination in laminate structures. A simplified model of the current delivered by an HPP generator is introduced, and its temporal evolution is related to the mechanical load applied to the laminate. Previously established delamination criteria, derived from a one dimensional wave propagation analysis using the method of characteristics, are reinterpreted to guide the design of an HPP generator. The required frequency and magnetic field amplitude are then expressed as functions of the laminate's acoustic and geometric properties. The results provide a set of design criteria for HPP generators in magnetic pulse disassembly applications, enabling effective and selective separation of bonded layers in multi-material systems.enMagnetic pulse delaminationInterfacial delaminationLaminate structuresHigh-power pulsed generator620670ConferencePapermagnetisches verfahrenDelaminationPulsgeneratorLaminatStrukturGrenzfläche
